Continuous integration and continuous delivery (CI/CD) is all the rage in the modern world of software development. But actually what is this pipeline process? It's a method or set of principles for which development teams implement and deliver code more frequently and reliably.

Kontron’s industrial temperature “SMARC-sAMX8X” module runs Linux on a dual- or quad Cortex-A35 i.MX8X SoC with up to 3GB LP-DDR4, up to 64GB eMMC, dual GbE controllers, and PCIe. Like Congatec’s Conga-SMX8X, Kontron’s SMARC-sAMX8X delivers NXP’s mid-range i.MX8X SoC package in an 82 by 50mm SMARC 2.0 form factor.

The best way to ensure student success is to give them agency and access to the best tools available. We highlighted those tools and practices in Opensource.com this year, and the results were amazing. As usual, open source continues to inspire innovation in both theory and practice. Our authors covered a broad range of topics within the education paradigm. We had something for everyone, including projects that could easily be applied in other settings. Here are a few highlights: read more

About three years ago, I shared an article on how to create a musical light show with the Raspberry Pi. I followed up a few months later with SSH into your Christmas tree with Raspberry Pi. A few things have changed since then, and this article is an update to the two originals. read more

I have been writing for Opensource.com for about four years and reading it since at least 2011. I am always amazed by the number and quality of the articles on the site. I have learned a great deal about many aspects of open source in general—and about Linux in particular. The articles we publish about Linux are always very popular and generate a lot of interest. Of the many Linux-related articles published on Opensource.com in 2018, these 13 garnered the most views.

The new Linux Mint is another step forward in what's already an outstanding Linux desktop distribution.

Sometimes, when you're executing a program, you might want to know its system resource usage. Like how much time the process spent in kernel mode and user mode, and other info. Thankfully, there exists a tool - dubbed time - that's specifically built for this purpose.

Continuous integration, continuous delivery, and continuous deployment (CI/CD) have all existed in the developer community for many years. Some organizations have involved their operations counterparts, but many haven't. For most organizations, it's imperative for their operations teams to become just as familiar with CI/CD tools and practices as their development compatriots are. read more

Shaun had asked that if I was willing to use AWK (not Bash), why not use Perl? It occurred to me that one might also ask: why not just use Bash? So, one more time into the void.

Prometheus is an open source monitoring and alerting system that directly scrapes metrics from agents running on the target hosts and stores the collected samples centrally on its server. Metrics can also be pushed using plugins like collectd_exporter—although this is not Promethius' default behavior, it may be useful in some environments where hosts are behind a firewall or prohibited from opening ports by security policy. read more

Greetings from another day in our 24-day-long Linux command-line toys advent calendar. If this is your first visit to the series, you might be asking yourself what a command-line toy even is.
